Like a full 12 hours with no wake ups! Yay!
But I was in that weird place last night where I went to sleep a little bit engorged but not quite enough to pump. He's been waking up at least once during the night to feed so I figured I'd be fine until then...when he woke me up 7 hours later my girls were huge and hard as rocks! I picked him up from his crib and immediately my shirt was soaked. I was so relieved to nurse him!
